      void run(FilterChange change)

      Emitted whenever the filter changed.

      Users of the filter should then check items again via Filter.match(GObject).

      GtkFilterListModel handles this signal automatically.

      Depending on the change parameter, not all items need to be checked, but only some. Refer to the Gtk.FilterChange documentation for details.
